This is what happens with SQL Server-returned errors and warnings and is consistent with how other drivers handle exceptions. The set of properties supported by jTDS is:. While doing this it times out, throwing the exception you see which means that jTDS was not able to get information about the running instances. Please note that this flag only alters the behavior of executeUpdate ; execute will still return all update counts. Where does one place an instance name in the connect string?
As the server itself does not return an SQL state code, the SQLMessage class associates native error numbers with SQL state codes actually there's a very comprehensive map there ; SQL Server originated errors and warnings that are not found in this map are given a default code of 'S', respectively ''.
Batch processing with executeBatch hangs or is unreliable on Sybase. CallableStatement output parameter getter throws java. The JNetDirect license precludes publication of performance test results.
Actually we do have benchmark results from two different benchmarks, both developed by large commercial SQL Server JDBC driver vendors to demonstrate the performance of their own drivers. Interface jTDS Implementation java. This is caused by triggers; replication is also implemented through triggers, so you will encounter this issue on replicated databases too.
For example, if you have a method that inserts a row into a table by creating a PreparedStatementusing it once and then closing it, your statement will be compiled only once for each Connectionno matter how many times you call that method.
In this case the driver will substitute the parameters locally and use a normal "execute procedure" SQL call; however, this jtvs of execution is less efficient than an RPC.
If you experience this problem with versions 0. You are required to use TDS 5. If you can't figure out why, ask your network administrator for help. Without the native SSO library installed you still have to provide the username and password jyds otherwise jTDS cannot determine user credentials.

Why do I still need to provide a username and password? If you'll look at the query you are trying to execute, you'll see that it probably returns an update count first, followed by a ResultSet. In our oppinion this is better than having a benchmark of our own, which could be designed in such a way as to give jTDS the edge. The name of the jTDS jar file may be jtds In this case the driver will be able to use an RPC succesfully as all the parameters are represented by parameter markers?
Web Design Anca Sinpalean. SSO in the distribution package for information on how to install it.
In this case it's the net. You can control the real batch size using the batchSize parameter; setting it to a non-zero value will break up batches into smaller pieces on execution, hopefully avoiding the problem.
As a general principle we try and keep synchronization to a minimum both for performance and deadlock reasons. Incorrect Behavior Itds output parameter getter throws java. When executing large batches on Sybase the client application may hang or the response time may vary considerably.
The client may be suspended if the system log fills so check that the log space is sufficient for the batch you are trying to load. Why do I get java.
Unable to load database driver - help with datasource profile
Of course, we will keep offering support on our SourceForge forums just as we did until now. As a sidenote, The Microsoft driver and probably jtd others, too "optimize" this behavior by skipping over the update count, which is wrong according to the JDBC spec.
There is a good side to this:
